Latency issues

Hi!
I'm getting consistently high latency in the game Destiny on the PS4. Sometime it checks with the server (some players are lag switching in game, and the server contact is part of the test to identify cheaters - I've even had a few players report me for my lag as they suspect I'm switching!).
My download speed (6.3Mb/s) is as expected for my local exchange. No issues with general web use and streaming videos on Netflix. I've had a local telephone engineer recently check the phone line (cheaper than opoenreach, but not cheap!), and that's all good.
Latency on speed tests are good, 22ms - 30ms.
I thought it may be a port issue. So I have tested the following:
UPnP on and off
Port forwarding on and off.
Static and Dynamic IP
Firewall disabled/enabled
PS4 in DMZ / not in DMZ
Ports forward on static IP's and DMZ.
If I test a port that looks open from outside the network (eg from canyousee me for TCP tests) then it results as closed or stealthed.
Here's a Netstat result for my PS4 currently 192.168.1.50, taken mid-game:

Hardware wise, I'm using an ASUS router (clean, no Tomato or Merlin) and a DrayTek 130 modem. I don't have easy access to a PC for flash based website diagnostics though.
The only thing I can think of is IP sharing, or another layer of NAT that I can't see. I'm pretty sure ISP's don't close ports as they did 10 years ago, and UDP 3074 is a common Xbox port (which also shows bungie's early thinking for a target platform!).
Any ideas or help would be appreciated.

Re: Latency issues

Hi,
A warm welcome to the forums.
Looks like your ADSL(1) line is synching at the top of ADSL capability, which makes the DATA speed of 6.3Mbps appear a bit slow,  Have you had a look to see if your exchange supports 21CN (ADSL2)?  See http://www.kitz.co.uk/adsl/adslchecker.php
Setting up a TBB BQM might be helpful - if you have not got a fixed IP address, you'll need to keep creating one each time the PPP session drops.  It might help identify if there is exchange congestion, which would not be surprising on a 20CN service.

Re: Latency issues

Yeah it is a 20 CN service. Sad
Open reach have  been saying a fibre roleout will be soon, or the cabinet is ready, for a year and a bit now. Not hit my street yet. My street is still poles and wires!
I'll set up a monitor. Good plan! Smiley

Re: Latency issues

Thanks for the BQM plot.  This has all the hall marks of exchange congestion.  This is going to need input from PlusNET staff (CRT) to identify if there is a better VLAN on your exchange and / or esclate the performance issue to BTw.

Re: Latency issues

If you can afford it you could consider switching to Max Premium (an extra £7.83 per month). As well as faster upload (832mpbs) it also gives you higher priority on the BT network which might well alleviate the affect of the contention.
Details of Max Premium can be found at http://trials.plus.net
You could try it for a month and then cancel it if it doesn't help.

Re: Latency issues

I like the idea of the Max premium. Happy to pay for a service as long as it delivers, and if there's no cancellation issues, then it's worth a shot. Thanks!
The monthly cost here is higher, as plus net rank it as an exchange with no competition, but I get the first 12 months free! Smiley
I'll take a look at switching to a static IP too, as it will make long term monitoring easier.

Re: Latency issues

One thing to watch out for with Max Premium: if the equipment you are connected to in the exchange is made by Marconi you might find that the ringing of an incoming phone call causes lots of errors and maybe disconnections - this only happens on Max Premium. I experienced this and it took a long time to sort out which was by getting my line connected to alternative equipment in the exchange.

Re: Latency issues

I'll remember that one! That problem must have been a nightmare to diagnose. I don't have the phone line plugged in, as we never use it. When Max Premium is setup I'll make sure I connect it.

Can you connect it now please and check out the line for noise?  Might as well ensure that there is no issue there!

1. It wasn't difficult to diagnose as when I contacted Andrews and Arnold with a view to taking up their Give us a month and we'll sort your problem broadband line or your money back they knew all about it and confirmed that my exchange had some Marconi equipment. The problem was getting Plusnet to accept and act on that information! They first came back to say that all the equipment in the exchange was Marconi even though I knew from AAISP that wasn't the case.
2. The problem occurred even if there was no phone handset plugged in. In fact the engineer reproduced the issue by connecting direct on to my line in the exchange with his test equipment.

Good point! I it checked with the engineer three weeks ago with his phone on both the master socket without the faceplate, but I didn't have a plus net phone line at that time.
We used his phone and I don't have an adaptor for my phone (its a smaller one), so I'll pick one up tomorrow and give it a double check!

Re: Latency issues

IP address changed (not an elegant disconnection Roll eyes) so I've updated the monitors and attached the older images:

Re: Latency issues

I've tested the phone line and it's fine Smiley
Plus net have got back to me on the upgrade already. Hopefully it well help! Smiley

Re: Latency issues

I would still ask questions about the utilisation of the exchange's back hauls.
